Pleurotus eryngii cultivation material containing pleurotus eryngii residues and preparation method thereof

Abstract

The invention discloses a pleurotus eryngii cultivation material containing pleurotus eryngii residues and a preparation method thereof, and belongs to the field of edible fungus cultivation materials and preparation methods thereof. The cultivation material is prepared from the following raw materials in parts by mass: 55.0-65.0 parts of a fermented main material, 8.0-12.0 parts of soybean meal, 6.0-9.0 parts of corn meal, 18.0-22.0 parts of wheat bran, 1.0-3.0 parts of lime and 1.0-3.0 parts of light calcium carbonate. The fermented main material is mainly prepared by mixing and fermenting bagasse, mushroom residues, corncobs and saw dust in a mass ratio of 1 to 1.1 to 2 to 2. The preparation method comprises the following steps: A, cleaning pleurotus eryngii residues; B, screening the pleurotus eryngii residues; C, prewetting; D, mixing, composting and fermenting the bagasse, residues, corncobs and saw dust; E, turning; F, screening the mixed material; and E, adding the soybean meal, corn meal and other auxiliaries. According to the cultivation material, the raw material cost can be remarkably reduced, and the cultivated pleurotus eryngii has the advantages of high yield, high quality, small budding amount, low pollution and improved biological efficiency.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation material and its preparation method, in particular to a pleurotus eryngii cultivation material containing pleurotus eryngii chaff and its preparation method. Background technique [0002] The total output and annual output value of edible fungi in my country are increasing year by year. China is the world's largest producer and consumer of edible fungi, accounting for 70% of the world's total annual output. It has become the fifth largest crop in my country's agricultural field after grain, oil, fruit and vegetables. Among them, Pleurotus eryngii is a large fleshy toadstool, also known as Pleurotus eryngii. It is a rare new edible fungus variety that integrates edible, medicinal, and dietotherapy successfully developed and cultivated in recent years. Pleurotus eryngii is rich in nutrition, rich in protein, carbohydrates, polysaccharides, vitamins and minerals such as calcium, magnesium, co...

Problems solved by technology

[0003] However, the production of Pleurotus eryngii in factories in my country is increasing rapidly in the total output, and the market demand for high-quality Pleurotus eryngii is also increasing year by year. Due to the limitations of investment level, technical level, and management level, the biotransformation rate of Pleurotus eryngii Low, high pollution rate, unstable yield and quality, high production cost, serious waste of fungus chaff

The cultivation material of Pleurotus eryngii is an important factor affecting the biotransformation rate, high pollution rate, yield and quality in the production of Pleurotus eryngii, and now the Pleurotus eryngii used by large and medium-sized Pleurotus eryngii companies has produced a chaff of chaff , mainly used as orchard machine fertilizer, did not exert great value; Pleurotus eryngii chaff is also used to cultivate other fungi, such as CN201410247438.X "A formula and preparation method for cultivating Pleurotus eryngii chaff to cultivate Agaricus bisporus" , but there is no use of Pleurotus eryngii chaff to cultivate Pleurotus eryngii, and there is no process of using the same variety of Pleurotus eryngii chaff and main ingredients to ferment and then use it to cultivate the same species of Pleurotus eryngii

Existing Pleurotus eryngii production enterprises need to spend a lot of manpower, financial resources, and transport capacity to send the pleurotus eryngii chaff to downstream enterprises for processing, and need to spend more cost to purchase raw materials such as corncobs and sawdust to prepare Pleurotus eryngii cultivation materials , it is impossible to recycle the chaff of Pleurotus eryngii within the enterprise
